[GUILT v2 10/29] Run test_failed if the exit status of a test script is bad.

[Per Cederqvist <cederp@opera.com>]

There were two problems with the old code:

 - Since "set -e" is in effect (that is set in scaffold) the run-test
   script exited immediately if a t-*.sh script failed.  This is not
   nice, as we want the error report that test_failed prints.

 - The code ran "cd -" between running the t-*.sh script and checking
   the exit status, so the exit status was lost.  (Actually, the exit
   status was saved in $ERR, but nothing ever looked at $ERR.)
